Traditional

Standard cement / sand screeds are a layer of material laid in situ and consist of bonded, unbonded, floating and heated construction. The screeding system is used for obtaining a defined level to receive final floor coverings such as ceramics, stone, carpet, linoleum, wood flooring, etc.

Traditional screeds can be used in hospitals, airports, schools, sports facilities, retail, residential dwellings and more. Traditional screeding can be produced either at a ready mix plant from various suppliers or on site using a forced action mixer, generally a screed pump.

CSC Screeding Ltd use screed pumps for all cementitious screeds and find this to give flexibility on site. The flexibility of site mixing has an advantage whereby variations in the substrate can often result in huge variances of material requirements. A screed pump has a 260 litre mixing vessel and having carefully calculated the volume to allow for the reduction due to mixing arms, blades, central bar and of course the void, we know just how much material is required to ensure the cement is gauged and therefore guarantee our mix will be as BS 8204 Part 1 2003. General mix proportions consist of either 1:3 or 1:4 Cement / Sand ratios.

The sand grading for floor screeding is BS EN 13139 class M grade and consists of a 0-4mm and 0-8mm grading. 0-4mm grading is generally used in the UK and is carefully mixed with the following cement classes:-

  • Ordinary Portland Cement CEM 1 42.5N conforming to BS EN 197-1.
  • Suphate resisting Portland Cement conforming to BS4027.
  • Portland Slag Cement CEM11/A-S or CEM 11/B-S conforming to BS EN 197-1.
  • Calcium Aluminate Cement conforming to BS 915-2.

CSC Screeding Ltd recommend that good quality cements are used and carefully mixed with the correct grade of sand, successful implementations can be achieved.
